Application August 31, 1940, Serial n. 355,074 3 Claims. (craze-51) Our invention relates to "containers and more particularly to the class known as one trip or single use containers which are :meant to be used but once and then to be thrown away. In accordance with our invention the container is especially constructed so as to prevent refilling and sale of the container with contents again.

One object of our invention lies in'the provision of a container which may be formed from transparent material such as cellulose or similar material.

A further object herein is to provide a container thatis capable of holding all and-like materials.

A further object is to provide a container which, while light inweight, has a high tensile strength.

A further object ie to provide a single trip orone use container which, havingbeen emptied will. give visible notice that it has been previously used, should anyone attempt to refill it and offer it for sale.

A further object is to provide a container having a spout formed from the top of the container, after same has been opened, for-guiding the flow of its contents, while the container is being emptied, and forming an integral part of the top of the container before it is severed'from the container.

A further object is to provide aseamless con tainer, wherein the contents are completely visible.

A still further object is to provide a.container which maybe manufactured and printed with suitable advertising matter as. may be necessary to identify its contents, then a plurality of the printed containers may be bottoms put in them, welded to the cylinder the 'bottoms then being wall, -forming, in'fact, a

A further object is to which mustbe substantially destroyed to remove its contents. a h I In accordance with the-present construction single use containers may be made in large quantitles, at low cost, so that they may have a consequent'wide use.

v The invention comprises a novel construction and arrangement of ,partshereinafter more speprovide a container merits of this invention could be made, without departing from the scope thereof, it is intended that all matter contained in the description, drawing, and claims shall be interpreted as illustrative and not in a limited sense.

The objects set forth hereinabove and other incidental ends and advantages will more fully appear in the progress of this disclosure and be pointed out in the'appended claims.

In the'drawing forming a material part of this disclosure similar reference characters designating corresponding parts throughout the several views in which: t

nested, and shipped to .the distributor where they are filled and have ciflcally described and illustrated in the accompanying drawing which refers particularly to'the exemplary embodiments of the invention. However, as many changes can be made in the above construction and many widely different embodi- Figure 5 is a'fragmentary sectional view of a second form of container. I

Figure 6 shows a handy means for severing the top of the trough to form the'spout on the first embodiment.

Figure 7 shows a third form of the container I wherein the top of the container is peaked but not conical, the top having one straight side, a continuation of the side wall of the container, which terminates in the front end wall of trough.

Figure. 8 is a fragmentary sectional view of a fourth form of container." 1

The container we have invented to meet the objects stated aboveconsists bf a container having a cylindrical body, made from some transparent' material, preferably cellulose acetate.- This container may be fabricated and welded or formed from a slug or other mass of material deposited within a properly prepared mold.

The cylinder side wall I is slightly tapered to- .ward the top ll which is conical in shapeand has an outwardly raised troughlike protrudence as shown in Figures 1, 2, 6. -This troughlike pro- 1 trudence has side walls I5 and a head 3 all of v which are continuations of the shell of the conical top portion II. The side walls l5 of the trough are provided with ascore! near where it merges with the conical top II, to permit easier severing of the upper portion thereof. The conical top may be provided with corrugations instead of being plain as shown in the drawing.

The side wall 1 is slightly tapered so as to pera wall lof the container is mit the containers being nested, when being shipped to the distributors. The side wall I at its lower end has an outwardly projecting offset 4 and a lower skirt portion 5 which extends downwardly. This skirtlike extension 5 of the side in excess to the length of the side wall 1 of the bottom 6. The bottom 6 has a downwardly extending side wall I therefrom and is crowned upwardly to withstand greater pressure and also for the same purpose-are ribs 9 arranged radially on the bottom, which are formed out of the bottom as shown in Figures 3, 4.

When the containers are filled at the distributors they are filled bottom side up. After the milk, oil or other substance has been put into the container, the bottom 6 is put in place, seated.on shoulder formed by offset-4 of the side wall of the container. Then the skirt portion 5, which is in fact a continuation of the offset portion of the side wall I and which is in excess to the length of the side wall I of the bottom 6, is formed over and'down or upwardly as viewed in Figure 2 on the skirt portion 1 of the bottom 6. When this has been done, suitable heat and pressure is applied and the-three thicknesses of the side walls are actually welded into a single thickness, thereby eliminating any seam or joint between the bottom 6 and the side wall I of the container.

To remove the milk, oil or other contents from the-container, any edged implement may be used to sever the upper portion of the trough, by merely inserting the implement into the scored portion 2 and cutting the top portion entirely off. When the upper portion of the trough has been severed, the portion which remains, forms a spout or funnel which guidesthe stream of contents as it flows from the container. This enables one to pour the contents into a small opening with certainty,

When the container is empty it may not be refilled because, due to the shape of the opening, it would be difficult to put ac'over on it and even then it would give visible evidence that it had been previously opened. The side walls l5 may also be made to taper slightly towards the top to make more diflicult the applying of a cover which in conjunction with the corrugated conical top would make it impossible to ever reseal it after it has been opened, as we have previously stated giving visible evidence that the container had been opened before. Thus when the upper portion is severed the container is substantially destroyed.

The fragmentary viewG shows another way-the top portion of the trough may besevered, consisting of two buttons l0, ll around which is wound a wire or other cutting agent, l3 which has a tab If fastened to one end thereof. To remove the contentsit is only necessary to place the cutting agent l3 into the scored portion 2 around the trough and pull. Because the cutting agent I3 is anchored on the bottom It] the pulling of the tab I! will cause the upper portion of the trough to be cut ofi'.

Figure '7 shows another modification of the container, in this view the apex of the peaked top is in line with the side wall of the container. The trough is formed out of the top and is also provided with a scored portion 2 which goes all around the trough. The top of the trough would be severed and the container destroyed in the manner previously described.

In Figure 5 a different form of container is shown. The cover I6 is provided with a score groove H which may be removed with any sharp implement. In Figure 8 a thin portion which may also be removed as is the cover shown in Figure 5. Y i

We claim:

1. A container of the kind described of cellulose material including a body and an integral conical top having an apex, and providing a bend at the junction of the top and body, said conical top being normally closed from the bend to the apex and having a narrow hollow rib protruding outwardly from said top and extending downwardly from the apex of the cone to said bend whereby removal of the upper part of the rib along its length provides a narrow pouring slot.

2. A container of the kind described of cellulose material including a body and an integral conical top having an apex, and providing a bend at the junction of the top and body, said conical top being normally closed frdm the bend to the apex and having a narrow hollow rib protruding outwardly from said top and extending downwardly from the apex of the cone to said bend whereby removal of the upper part of the rib along its length provides a narrow pouring slot, said rib being provided with a peripherally extending groove forming aweakened guide line for a severing device.

3. A container of the kind described of cellulose material including a body and an integral conical top having an apex, and providing a bend at the junction of the top and body, said conical top being normally closed from the bend to the apex and having a narrow hollow rib protruding therefrom and extending downwardly from the apex of the cone to saidbend whereby removal of the upper part of the rib along its length provides a narrow pouring slot, said rib being provided with a peripherally extending groove forming a weakened guide line for a severing device, and a severing strand having one end secured to the body adjacent the lower end of the rib and of a length adapted to pass around the rib.
